Drupal 7 audioconverter module failed - libavcodec52 - which codec for Debian squeeze ?
7 décembre 2012, par MeggyI am using the audioconverter module with the audiorecorderfield module in Drupal 7. Though it was working previously, I just recently noticed that the audioconverter module has stopped converting wav files to mp3. Here's the error in my logs ;

I can see the wav file is created by the audiorecorder module but the audioconverter module is failing on the conversion.
Does anyone know which codec I should use in Debian 6 Squeeze ?

ffmpeg watermark bottom right corner
8 décembre 2012, par John DoeI am not sure why, but I cannot seem to get a watermark rendered on the bottom right corner of my video using ffmpeg.

ffmpeg –i faded.mov -vf "movie=logo.png [watermark]; [in][watermark] overlay=(main_w-overlay_w-10)/2:(main_h-overlay_h-10)/2 [out]" outputvideo.mov
I see the following output :
